new install, physical path is incorrect

Hi everyone, this is a new zen cart installation I'm having trouble with:

Preface
I dont know PHP, dont know anything about SQL, but I am persistent and kind of good at following directions...(we'll see):

**Situation: **
At the "system setup" step, the installer does not accept my zen cart physical path:
"Physical path is incorrect"

the physical path I'm trying is:
home/engrave/public_html/istore

(made zencart's folder name "istore")

I have also tried just about ever permutation (you should see my browser's auto-fill when I start trying paths!:clap: )

What I've done so far:
• I followed the installation steps line by line double checking the permissions for the uploaded files...
• I had to make a .htacess file that I put in the zen cart main directory, this is what I put in the file:
php_value session.use_trans_sid off
php_value register_globals off
#php_value register_globals off
php_flag session.use_trans_sid off
<Files ".ht*">
deny from all
</Files>
(I have no idea what this code means but I copied it from the manual)

Other info:
my provider is IPower web hosting
MySQL 4.0.16 running on localhost as engravee@localhost
Using transmit (OS X) to edit the files on my server.
:frusty:

Thanks guys, Adrian.

See if this path works better:

/home/engrave/public_html/istore/

no luck... I tried:
/home/engrave/public_html/istore/
and
/home/engrave/public_html/istore
and
home/engrave/public_html/istore

Thanks for the reply...

Hold on a minute, I tried again:

/home/engravee/public_html/istore

and got back:

Not Acceptable

An appropriate representation of the requested resource /istore/zc_install/index.php could not be found on this server.

Apache Server at engravee.com Port 80

I'd say this is something rather than nothing, I'm investigating. If you might have any tips I'd appreciate it!

Thanks so much...

Got it. I ended up re uploading the zc installer folder, seemed to fix everything.
